以粉煤灰为改性组份的石膏粉煤灰胶结材研究

Study on gypsum fly ash binder in which fly ash acts as modified component

在石膏体系中掺入适量粉煤灰，通过对粉煤灰活性的充分激发，可显著改善石膏建材的微结构与耐水性。研究了石膏粉煤灰胶结材（以下简称ＧＦＢ）的配制原理与方法，胶结材性能及应用，分析了胶结材水化硬化特点及粉煤灰的改性作用。为同时利用两种废渣、扩大粉煤灰在建材工业中的应用提供了一条新途径。

The micro structure and water resisting of gypsum building materials can be improved greatly by adding fly ash to gypsum system and activating its activation.The making principle and method,the properities and practical use of gypsum fly as binder(be called GFB in short)had been studied.Authors analysed the hydration hardening characteristics of the binder and the modified effect of fly ash.Authors gived a new way of utilizing two industrial residues and enlarging the use of fly ash in building material industry.
